We have thistles in our landscape beds. From our research to control this weed they should be sprayed with 2 4-D. This method will also kill the other plants. Is there a method other than this spraying that would control the thistles without harming the good plants?

Why did this evergreen tree die? We realize that this particular one is past saving, but we would like to know how to keep the others from developing this issue. Can anyone suggest any ways to prevent the loss of our other trees?

I have had sod placed in my backyard twice in the last three years. Each time it died. I have had success growing grass in the yard for years before the sod was laid. I watered it as directed. The professional lawn service personnel have told me the grass died because the yard is heavily shaded. I don't believe that. My neighbor has healthy grass even though he has a huge maple tree that shades his backyard. Before I spend any more money on the yardI need to know why the grass won't grow. Can you help?

I am sending this from the SDSU Associate Director's office. I had a phone call from an elderly gentleman wondering about what to spray on strawberries to "get rid of the bug that walks across the blossom" and causes the small hard strawberries. If you can give me an answer I can call him with the information.
